system has an SB0090 (audigy), works 100% no problems at all.

channels 6/7 are used in winamp directsound output update: first I can confirm now that it is the kx driver, and that it also happens in version 3549, but best of all I found the reason that the leak happens - when winamp directsound hardware acceleration option is enabled - no leaks when disabled update 2: switched to version 3548, memory leak is no longer instant but it is still there, here is how to produce it: while hardware acceleration is enabled keep pressing play repetitively or do alot of seeking within the file while watching your nonpaged pool (or just hold enter on the file) - you will see that it increases by approximately 100 kb for every time play/seek is done this probably explains why programs such as games that play many sounds at once cause the same leak - over time or not in none of the cases the memory is reclaimed after the program (and any other audio programs) is closed does not leak at all in WAVE/ASIO/KS mode strange that in winamp it only has an effect with an mp3, FLAC and WAV appear to be unaffected.... update 3: this "smaller" leak continues all the way to version 3534f which is the oldest I managed to test, will have to try even older versions because so far there is no version without the leak. update 4: the leak does not exist in winamp 2.91, only in 5.02, maybe something in the way the different versions of directsound output plugins work ?
